Definitions

  • the invention relates to a vehicle body with a resiliently mounted front hood, each having a hinge between the vehicle body and a side edge of the front hood so that it can be opened about a pivot axis defined by the hinges, and with at least one resilient under load assembly at each side edge for supporting the front hood on the vehicle body, wherein the structural unit is designed as a stable, but plastically deforming crash box, which gives way above a certain load during an impact-like force.
  • a generic prior art shows the WO 00/72101. This shows a compliant with impact load assembly, which can be addressed in the broadest sense as a crash box. Specifically, it is a provided with a slot, flat piece of sheet metal between a hinge on a strut connected to the hood and a body-mounted strut. The piece of sheet metal consists of two tabs, which laterally enclose the slot.
  • the tab shown is insufficient for pedestrian protection, because the tabs buckle when loaded to the side and fold once.
  • the case acting bending forces are relatively small, or fall as the convolution progresses, from an initially high value rapidly, so that the energy consumption is relatively low overall. This means that the head impact speed can not be completely reduced to the maximum deformation path of the tabs, so that the head is finally jerkily delayed.
  • the invention is thus based on the problem of designing the component so that it is stable enough to withstand static loads, but yielding enough to be able to avoid jerky loads emanating from a head striking the bonnet, so that one for the head just bearable strength level prevails.
  • the solution to this problem consists in a vehicle body according to the preamble of claim 1, which is characterized in that the crash box consists of a tube whose longitudinal axis is arranged substantially parallel to the direction of force and the pipe edges, which are interconnected by side surfaces.
  • Such crash boxes are known in much larger dimensions than holders of vehicle bumpers or as a vehicle side member.
  • these are tubes with a closed square cross section, which are arranged so that they are loaded in a longitudinal direction. If a certain load is exceeded, the edges of the tubes alternately buckle inwards and outwards, whereby the side surfaces connecting the edges fold into folds. Since these processes are irreversible, the energy inherent in the shock is consumed. Since the edges give the pipe itself a certain rigidity, can it can be loaded statically without buckling. It is thus suitable also to serve as a carrier or composite strut within a structure. The tube-like structure results in further parameters, so that the basic stiffness and the energy absorption can be even better coordinated with an impact load.
  • the hinge has at least one torsionally resilient crank arm as a resilient unit.
  • the crash box is an integral part of the hinge and is arranged between an upper strut and a lower strut of the hinge, which are connected to each other via at least one folding lever. This arrangement has the advantage that the usual construction of the hinge need not be changed. Rather, it only needs to be integrated into the space between the two struts a crash box.
  • hinges which have a shorter and a longer folding lever, so that the front hood can be folded when unfolding about a pivot axis, which experiences an offset
  • the crash box is located near the closely spaced joints of the folding lever on the upper strut, so that the introduced into the hinge impact forces are optimally absorbed
  • One-armed hinges have a folding lever extending in an arc, wherein the one end of the folding lever is fixedly connected to an upper strut connected to the front hood, wherein the front arch portion adjoining this end extends approximately perpendicular to the front hood and wherein the other end of the Folding lever is rotatably mounted on the body.
  • the crash box is formed in the front bow section.
  • the hinge 1 consists of an upper strut 2, which is welded or screwed to the front hood, and a lower strut 3, which is bolted to the vehicle body. Between the two struts 2, 3, two folding levers 4, 5, which are each mounted in joints 6, 6 ', 7, 7' rotatably mounted on the struts 2, 3 extend. So that when opening the bonnet moves up and forward to avoid a collision of its rear edge with a frame enclosing the front hood, the one folding lever 4 is longer than the other folding lever 5 and the joints 6, 6 'on the upper strut 2 closer together than the joints 7, 7 'on the lower strut 3. In this way, the pivot axis of the front hood undergoes an offset to the front when unfolded.
  • Fig. 1 is located between the two struts 2, 3 in the region of the closely spaced joints 6, 6 'on the upper strut 2, a crash box 8.
  • This consists of an upper plate 9 and a lower plate 10, the lie flat against the struts 2, 3.
  • the lower plate 10 is welded to the lower strut 3.
  • the upper plate 9 forms a stop for the upper strut 2, whereby the closed position of the hinge 1 is defined.
  • the crash box 8 is located between the lower strut 3 and the vehicle body, to which it has a paragraph not shown here.
  • the closed position of the front hood and thus the closed position of the hinge 1 is ensured by stops.
  • a stop 13 is shown schematically in Fig. 2.
  • crash box 8 The execution of the crash box 8 is the same in both cases.
  • the two supporting walls 11, 12 can also be supplemented by further supporting walls. These can be parallel to the shown but also perpendicular thereto and with these form a square in cross section tube.
  • FIG. 3 shows an embodiment of the invention for a hinge 1 with a folding lever 15.
  • this has an arcuate shape, so that the hinge joint 16 can be arranged below a body panel in extension of the front hood.
  • the hinge joint 16 When unfolding the front hood of the folding lever 15 engages with its arc shape around the front hood facing edge of the body section around.
  • the front arcuate portion 17 in the closed position of the bonnet in approximately perpendicular - ie in the direction of Kopf Stammschlages - runs, he is capable of receiving an energy absorbing device or crash box 8.
  • a solution in which the crash box 8 has retaining walls 11 is shown in FIG.
  • the folding lever 15 is separated in the front arc section 17 and the crash box 8 is inserted with a plurality of mutually parallel support walls 11 which extend between two plates 9, 10, with their outer sides, the two ends of the separation are connected to the crash box 8.
  • FIG. 4 Another variant of a crash box which is not part of the invention is shown in FIG. 4.
  • the crash box 8 consists of a single support wall 11, which is a portion of the folding lever 15.
  • the support wall 11, that is, a corresponding portion in the front arcuate portion 17 of the folding lever 15, provided on both sides with transverse beads 18 which cause the folding lever 15 is compressed like an accordion in a jerky load.
